SHEPS SN12 CLASSIC EQUALIZER MODULE
Product Description
This is a more sophisticated equaliser in a 12 inch high module case with Hi Q on the two mids, and has peaking and shelving curves selectable on both the HF and LF bands. It has a Dual concentric sensitivity switch which has a stepped Mic sensitivity on the outer with a Line trim potentiometer in the center. Mic and Line is selected by a toggle switch or it can be remotely selected. It is available with either the Class A/B output stage or with the option of Mr. Rupert Neve's Class A output stage and special output transformer. This version is called the SR12. The Class A/B version is usually purchased for the versatility and transparent sound of its Equaliser section. The Version which has Rupert Neve's Class A output stage has the best of both Worlds, but of course is slightly more expensive. Can be supplied fitted with 22 way Amphenol connector (with pre and Post Eq ) or with 18 way Amphenol so that it can be retrofit into Neve Consoles which had 1081 or 1064 Equalisers.
